Modern buildings of private houses are pleased with their diversity. Previously, thinking over the construction of your own housing, people knew exactly: take the brick, we choose the rest in the course. Today, the situation has changed somewhat, the interest of the newly minted developers shifted towards porous gas-silicate blocks. This material is good in that it has a practically perfectly smooth surface, has good thermal insulation properties, convenient and easy to lay. Another of his indisputable advantage is the use of a special fastening composition, on whose features further speech and go.


Glue used to build housing from gas-silicate blocks is a universal mixture of elements that allow the most simply and quickly combed a porous building material.

The main features of such adhesive are its main advantages over classical cement mortar:

  • Low thermal conductivity. This is due to the lack of emptiness in the seams and the so-called “cold bridges”.
  • High grip percentage with any surface. Adhesive universal for any blocks: Classic and ceramic brick, foam and aerated concrete and other.
  • Economical flow. Due to the minimum thickness of the layer for setting (no more than 7 mm), the height consumption is less than the consumption of the cement mortar 6-8 times, which is significantly reflected at the total cost of building materials.
  • The versatility of this composition is that it can be used as a means for aligning the surface in a horizontal and vertical direction.
  • Comfort in operation. The main convenience of glue for gas silicate blocks is that it is easily kneaded, simply applied, and within 15 minutes after applying the position of the block can be changed.
  • The presence of mixtures for working in the cold season.

Of course, with such quantities of advantages, it is very difficult not to look at the main flaws of glue for porous surfaces. Among others, for example, it is often indicated by demanding to practically ideal surface levels. And also the high cost of the bag – from 150 to 250 rubles for 25 kg. However, all these disadvantages are compensated by the advantages of the mixture.

Due to the large variety of manufacturers and forms of release of glue for gas-silicate blocks, you can choose the most appropriate option.


The production of glue is concentrated on two main groups: winter and summer options. Since on the territory of our country to build a house from gas silicate blocks may be needed at any time of the year, this plus is very happy.

Frost-resistant glue should be used at a temperature not higher than +5 and not lower than -15 degrees Celsius. This guarantees the maximum effect, no errors, shrinkage and cracks. For example, if the process of drying the adhesive occurred at a temperature of 10-20 degrees, there is a risk of cracks in the seams and, as a result, the deprivation of a gas silicate of its main advantage is low thermal conductivity. Thus, all heat will go through the walls.

Typically, aerated concrete and other porous blocks are not afraid of a sharp temperature difference. Here the main role is already playing the correct technology of applying their solution, the use of reinforcement for fixing the structure as a whole, T. E. Accurate following instructions described on a bag with a mixture, as well as advice of professionals.

Another enjoyable innovation of recent years has become the release of glue for gas silicate blocks in foam format. As well as assembly, glue-foam sold in the cylinders for which a special construction “gun”. The only “but” in the use of this type of glue for porous structures is its unfinished testing. There is no data on how long such a ready mix can be served and how efficiently.

As you know, each kulik praises his swamp. The same happens with the leading manufacturers of construction mixtures. There are many of them and they all very actively spread their products, calling her the most. Let’s try to figure it out.


The ideal option is the acquisition of gas-silicate blocks and glue for them from one manufacturer. This immediately increases the efficiency and strength of the future building. But some companies may intentionally put a price higher on their building mixes. Therefore, experienced professionals know who is better to acquire blocks, and who has glue. Let’s figure it out “Introductory”.

AEROSTONE – mixture from Dmitrov plant of aerated concrete products. Produced in winter and summer modifications. Cement-based product with the addition of water-retaining polymer add-ons.

“Obudova”. It is considered one of the best adhesives for working in frosts for a small price – about 120 rubles per bag. Easy to mix even in -15, does not give a shrinkage, does not affect the environment and atmospheric phenomena.

“Prestige” It is convenient for use not only with gas-silicate blocks, but also with other porous plates. The manufacture of adhesive mixture leaves a minimum of time.

Bonolit Noginskaya company “Bonolith – Construction Solutions”. This glue is absolutely environmentally friendly and safe. Does not have toxic artificial impurities. You can use both for laying blocks from the outside and internal works.

Unic Uniblock – one of the most popular manufacturers of glue and gas-silicate blocks. The main advantages of this mixture is a complete set of characteristics that make it possible to make the most efficient, functional and durable building:

  • high thermal insulation properties;
  • resistant to moisture and temperature differences;
  • Excellent plasticity allows you to change the position of the block for 20-25 minutes after installation;
  • environmental friendliness;
  • Medium price category.

Aeroc produced by an enterprise for the manufacture of cellular concrete “Aeroc SPB” in St. Petersburg. The high strength of the finished material and unique thin layerness (up to 3 mm) takes out this glue to the leading positions of the building materials market in Russia.

“Win” – multicomponent mixture based on cement, quartz sand and additional polymer inclusions. The composition of this glue almost completely repeats the composition of the main gas-silicate blocks presented today in the Russian market. It is this quality that allows it to be as accurately and quickly and quickly adjusted with the surface, forming a unique monolithic structure, not afraid of moisture, frost and heat.

These are the main well-known glue manufacturers for gas-silicate blocks, which confirmed their title of the best years of use. This list did not get similar to the properties of the mixture: Thermocube (g. Kostroma), Poritep (g. Ryazan), “Eco” (g. Yaroslavl), which are less popular, but are not inferior to their more famous “colleagues”.

Choose a good mix easy. Relying on the experience of professionals, your own needs and flair, you can get a great result for a little money, but excellent quality. The main thing is to comply with all the necessary requirements and technology.


When choosing one or another glue brand, follow the following criteria.

  • Manufacturer’s name. Very often there are conquered one-day firms that produce poor-quality promotional materials that turn out to be fiction and do not bring the desired result, and sometimes harm the construction. So as not to be mistaken and not to get into the bait of fraudsters, it is better to trust the famous and proven trademarks, and also remember that the quality product can not cost cheap.

  • Packaging and storage conditions. When choosing a product in stock immediately pay attention to how it is stored. Increased indoor humidity, sharp temperature change, packaging damage, bag with blurred letters and company logo – all this explicit witnesses of poor quality mixture. This material is so good if it is compliance with the rules of its storage, as far as it is disgusting, when at least one parameter does not correspond to reality.
  • By weight. Never agree to acquire glue for gas-silicate blocks without packing. No one will be able to give you a one hundred percent guarantee that there are no low-quality impurities.

    Deciding with the brand-producer of glue for gas silicate blocks, you can proceed to the calculation of the consumption of material. Often, all companies indicate this amount on packages of their products, however, this information is only a reference, so for each individual case it is necessary to calculate the consumption of glue to the cube blocks individually.

    The main parameter on which the amount of calculation of the solution per 1 m3 depends is the thickness of the layer. If this indicator is no more than 3 mm, the amount of glue on average will be from 8 to 9 kg per meter cubic. With the thickness of the layer from 3 mm and more consumption of the finished mixture increases 3 times and amounts to 24-28 kg on the same surface area.

    To somehow optimize the consumption of glue, you can resort to the following technological tricks.

    • Surface preparation. One of the important criteria for laying gas-silicate blocks using specialized glue is ideal evenness. The smaller blocks, the less the consumption of the construction mixture will be.
    • Compliance with solutions. Just take and knead the glue for laying gas-silicate blocks, like dough for pies, will not work. Here is also there is a system: firstly, the adhesive powder is poured directly into the water scored in a clean capacity (plastic or galvanized bucket fit perfectly); Secondly, the stirring occurs in two stages, with a slight break (5-7 minutes, no more); Thirdly, it is not necessary to bring the large volume of the mixture immediately, since it can not have time to use it until the moment of frozen (most manufacturers this time is limited to 2 hours).
    • Application methods Also play an important role in reducing the flow of glue. For example, the main tool for laying the mixture is a spatula with a tooth. Laying gas-silicate blocks better than 10 minutes after applying glue, tightly pressed and tapping the rubber hammer over the surface.

    The first number of blocks never put on glue. Always under the initial “string” of the whole design foundation: concrete screed, screw piles and other. So the whole building will be much more stable and durable.

    These are the main tricks that need to be used in operation to minimize glue consumption for gas-silicate structures without prejudice to quality.

    In order to accurately arrange the blocks, and between them – layers of glue, it is necessary to use mixtures intended for a particular case: for internal or external work, for laying gas silicate blocks at high or low temperatures.

    It is also necessary to remember that the minimum time to frozen glue in a block or panel design is. But the best and final result is observed no earlier than third days after laying.

      Compliance with the main indicators of temperature and humidity allows the construction of a gas-silicate design Using special glue quickly, simple and high-quality even a novice builder who has no additional skills or education. Of course, it is very important to enlist the support of professional masonry and experienced builders in this difficult thing, then only rejoice and enjoy the positive result of your own efforts.
